1:27 is respectable (with current track). 1:16 is already quite good. Presumably either one of these would be somewhat better with an express service, too.
Are any of these improved by removing some of the current level crossings? Or are those already good enough to not have an impact?
Level crossings with crossbucks can be used for Class 6 tracks (110mph, 177km/h), according to my understanding of Transport Canada rail regulations, so none of them would need to be removed. The only modifications I assumed for my numbers was getting ride of the small number of curves that were too small a radius.
